The commite6fe3f422b("sched: Make multiple runqueue task counters 32-bit") changed nr_uninterruptible to an unsigned int. But the nr_uninterruptible values for each of the CPU runqueues can grow to large numbers, sometimes exceeding INT_MAX. This is valid, if, over time, a large number of tasks are migrated off of one CPU after going into an uninterruptible state. Only the sum of all nr_interruptible values across all CPUs yields the correct result, as explained in a comment in kernel/sched/loadavg.c. Change the type of nr_uninterruptible back to unsigned long to prevent overflows, and thus the miscalculation of load average.
